StupidMCU

"It's not stupid, its advanced." -- Purple Tallest

What is this?

StupidMCU is a derivative of OpenH323's OpenMCU program. An MCU is a conferencing server for H323 calls - multiple people can join rooms and chat to each other. You can either use a desktop client, such as Microsoft Netmeeting or GnomeMeeting, or a voice over IP gateway, such as a cisco AS5300 or AS5400.

StupidMCU has a bunch of changes that I needed for my day-time job. Note that I only care about/need audio, not video, so I've not done much on the video side - I have no idea if it still works (it should, but I have no video capture hardware to test with)

Major changes so far (and status of the changes)

• Using PHTTPServiceProcess as a base class. This makes it a 'service' type process, with an inbuilt HTTP server. This is there, but the 'Parameters' page isn't quite hooked up right. I need to do more investigation as to why - for now, there's no link to it from the root page.
• Room ownership. Members of a room can be one of two types - a "member" (normal) or an "owner". Owners get additional functionality. In future will add a new type "listener" who are permanently muted.
• Support user input (keypresses on the phone keypad) - functions currently implemented include user muting (user can mute/unmute self) and room muting for owners - no-one but an owner can speak when an owner has muted the room.
• Support calling out to an XMLRPC server when someone enters or leaves a conference. On entry, the server passes information in this table and gets back info like this table. When a user leaves a conference, the call token is passed to the XMLRPC leave method.
• "Room" data structure, rather than just a dictionary of room name to members. Partially done.
• probably other stuff...

Status

This project is now here for historical interest only. I doubt the patches apply cleanly to openh323 any more - if you want to take them and update them, more power to you.

It seems to work (for me). As noted above, I have little use for the video stuff, so if someone wants to work on this and send me patches, that's fine. There's almost certainly bugs in the code - I'm still feeling my way around the (massive) openh323 class libraries.

The code

Code is released under the MPL, as is the standard openmcu.
